## 7364 Federal Register / Vol. 70, No. 28 / Friday, February 11, 2005 / Notices **ENVIRONMENTAL PROTECTION AGENCY**  **[OPPT–2004–0130; FRL–7692–1]** 

### Fifty-Fifth Report of the TSCA **Interagency Testing Committee to the Administrator of the Environmental**  **Protection Agency; Receipt of Report and Request for Comments**  **AGENCY** 

### : Environmental Protection Agency (EPA). **ACTION** 

### : Notice. **SUMMARY** 

### : The Toxic Substances Control Act (TSCA) Interagency TestingCommittee (ITC) transmitted its FiftyFifth Report to the Administrator of EPA on December 8, 2004. In the 55 th 

### ITC Report, which is included with this notice, the ITC is revising the Priority Testing List by adding a category of high production volume (HPV) orphan chemicals and requesting that EPA add these chemicals to the TSCA section 8(a) Preliminary Assessment Information Reporting (PAIR) rule and the TSCA section 8(d) Health and Safety Data Reporting (HaSDR) rule. The ITC is also removing the following chemicals from the Priority Testing List : 3-amino5-mercapto-1,2,4-triazole; glycoluril;benzenamine, 3-chloro-2,6-dinitro-N,Ndipropyl-4-(trifluoromethyl)-; stannane, dimethylbis[(1-oxoneodecyl)oxy]-; benzene, 1,3,5-tribromo-2-(2- propenyloxy)-; and1-triazene, 1,3- diphenyl-.]. Since the 55 th 

### Report was ITC transmitted to the Administrator and made publicly available on http:// www.epa.gov/opptintr/itc/, five HPV orphan chemicals have been removed from the Priority Testing List because chemical manufacturers committed to prepare robust summaries for these chemicals in response to the HPV Challenge Program. The ITC encourages other manufacturers to make similar commitments so their chemicals can be removed from the Priority Testing List and potentially avoid being added to PAIR and HaSDR rules. **DATES**

The Toxic Substances Control Act (TSCA) (15 U.S.C. 260l et seq .) authorizes the Administrator of the EPA to promulgate regulations under section 4(a) of TSCA requiring testing of chemicals and chemical groups in order to develop data relevant to determining the risks that such chemicals and chemical groups may present to health or the environment. Section 4(e) of TSCA established the ITC to recommend chemicals and chemical groups to the Administrator of the EPA for priority testing consideration. Section 4(e) of TSCA directs the ITC to revise the TSCA section 4(e) Priority Testing List at least every 6 months. A. The ITC’s 55 th

Background

The ITC was established by section 4(e) of TSCA ‘‘ to make recommendations to the Administrator respecting the chemical substances and mixtures to which the Administrator should give priority consideration for the promulgation of rules for testing under section 4(a).... At least every six months ..., the Committee shall make such revisions to the Priority Testing List as it determines to be necessary and transmit them to the Administrator together with the Committee ’ s reasons for the revisions ’’ (Public Law 94

–469, 90 Stat. 2003 et seq ., 15 U.S.C. 2601 et seq .). ITC Reports are available from the ITC ’ s web site ( http://www.epa.gov/ opptintr/itc/ ) within a few days of submission to the Administrator and from the EPA ’ s web site http://www.epa.gov/ fedrgstr/ after publication in the Federal Register . The ITC produces its revisions to the Priority Testing List with administrative and technical support from the ITC Staff and ITC Members and their U.S. Government organizations, and contract support provided by EPA. ITC Members and Staff are listed at the end of this report. II. TSCA Section 8 Reporting A. TSCA Section 8 Reporting Rules

Following receipt of the ITC ’ s Report (and the revised Priority Testing List) by the EPA Administrator, the EPA ’ s Office of Pollution Prevention and Toxics (OPPT) may add the chemicals from the revised Priority Testing List to the TSCA section 8(a) Preliminary Assessment Information Reporting (PAIR) and TSCA section 8(d) Health and Safety Data Reporting (HaSDR) rules. The PAIR rule requires producers and importers of chemicals added to the Priority Testing List to submit production and exposure reports ( http://www.epa.gov/opptintr/chemtest/ pairform.pdf/ ). The HaSDR rule requires producers, importers and processors of all chemicals added to the Priority Testing List to submit unpublished health and safety studies under TSCA section 8(d) that must be in compliance with the revised HaSDR rule (Ref. 1). All submissions must be received by the EPA within 90 days of the reporting rules Federal Register publication date.

## 7367 Federal Register / Vol. 70, No. 28 / Friday, February 11, 2005 / Notices B. ITC ’s Use of TSCA Section 8 and Other Information

The ITC ’ s use of TSCA section 8 and other information is described in previous ITC Reports ( http://www.epa.gov/opptintr/itc/ rptmain.htm/ ). C. Previous Requests to Add Chemicals to the TSCA Section 8(a) PAIR Rule

In its 53 rd Report, the ITC requested that EPA add 3 pyridinamines and 20 tungsten compounds to the TSCA section 8(a) PAIR rule (Ref. 2). On December 7, 2004, EPA issued a final rule, pursuant to TSCA section 8(a) requiring producers and importers of these 23 chemicals to report production, importation, and exposure data to EPA (Ref. 3). D. New Requests to Add Chemicals to the TSCA Section 8(a) PAIR and 8(d) HaSDR Rules

In this report, the ITC is requesting that EPA add the HPV orphan chemicals listed in Appendix A to the TSCA section 8(a) PAIR and 8(d) HaSDR rules. The ITC is requesting that these HPV orphan chemicals be added to the TSCA section 8(a) PAIR and 8(d) HaSDR rules because no voluntary studies have been submitted to the EPA in response to the HPV Challenge Program ( http:// www.epa.gov/opptintr/chemrtk/volchall.htm/ ). III. ITC’s Activities During this Reporting Period (May to November 2004)

During this reporting period, the ITC reviewed the reports submitted in response to the June 11, 2003, PAIR rule (Ref. 4) and the May 4, 2004, TSCA section 8(d) HaSDR rule (Ref. 5). The ITC is continuing to review these reports.

The ITC also met with EPA to discuss procedures for making data publicly available on HPV orphan chemicals (HPV chemicals for which no sponsors have volunteered to develop and submit robust summaries to the EPA). The ITC ’ s discussions with EPA are described in section IV. of this report.

As noted in the 51 st and 54 th ITC Reports (Refs. 6 and 7), the ITC continues to request the following information on vanadium compounds:

1. Recent non-CBI estimates of annual production or importation volume data and trends, and use information, including percentages of production or importation that are associated with different uses.

2. Estimates of the number of humans and concentrations of vanadium chemicals to which humans may be exposed in each relevant manufacturing or processing scenario.

3. Health effects data including pharmacokinetics, genotoxicity, subchronic toxicity, reproductive and developmental toxicity, and any human data from occupationally exposed workers.

The ITC seeks this information in order to adequately assess the extent and degree of exposure and potential hazard associated with the various forms of vanadium.

In addition, the ITC is concerned that some of these compounds may be released into fly ash ponds at power plants, petroleum and chemical refineries, and mining sites and could be toxic to avian and wildlife species as exemplified by a recent report of dead and dying Canada geese at a petroleum refinery fly ash pond in Delaware. In these geese, the vanadium concentrations in pooled liver and kidney samples were 57 and 226 μg/gram (g) dry weight, respectively. Background concentrations of vanadium in various tissues of higher vertebrates, including waterfowl, rarely exceed 1 μg/g dry weight. Limited data are available on vanadium toxicity in birds and other wildlife making it difficult to interpret the findings from the geese die-off.

The ITC knows that vanadium is released into impoundments at 172 facilities in 33 states and that the TRI does not have vanadium concentrations for these impoundments. The ITC is soliciting data on concentrations and species of vanadium compounds in impoundments at power plants, petroleum and chemical refineries, and mining sites and information on the use, release, and presence of vanadium compounds at these facilities. The ITC needs these data and information to determine if avian wildlife in the vicinity of the 172 facilities are at risk from exposure to vanadium compounds. If you have any questions regarding the applicability of this action to a particular entity, consult the technical person listed under **FOR FURTHER INFORMATION CONTACT**  . IV. Revisions to the TSCA Section 4(e) Priority Testing List A. Chemicals Added to the Priority Testing List: HPV Orphan Chemicals

1. Recommendation . EPA requests that the ITC add the category HPV orphan chemicals listed in Appendix A of this report to the Priority Testing List to obtain importation, production, use, and exposure information as well as unpublished physical/chemical property, environmental fate, health effects, and ecological effects information to meet U.S. Government data needs.

2. Rationale for recommendation . While the success of the HPV Challenge Program has been significant, hundreds of chemicals that were eligible for sponsorship in the Program continue to remain unsponsored. These chemicals are referred to as ‘‘ orphans. ’’ There is little or no publicly available information regarding the potential hazards associated with these chemicals. EPA remains committed to obtain basic screening level hazard information on these chemicals through voluntary sponsorship, as well as through TSCA information gathering and test rules, as necessary.

3. Supporting information . In developing the list of HPV orphan chemicals presented in Appendix A of this report, EPA considered all of the HPV orphan chemicals and then removed selected HPV orphan chemicals. The HPV orphan chemicals presented in Appendix A of this report do not include those HPV orphan chemicals that:

a. Had 2002 Inventory Update rule reported production/importation volumes > one million pounds ( http://www.epa.gov/ oppt/iur/iur02/index.htm/ ) and were proposed for testing in the first HPV test rule (Ref. 8). b. Meet the ‘‘ No Longer HPV ’’ criteria (i.e., chemicals with production/importation volumes < 1 million pounds based on 1998 and 2002 Inventory Update Rule data ( http:/ /www.epa.gov/oppt/iur/iur02/index.htm/ )). c. Are being considered for a second HPV TSCA section 4 test rule because they may meet the TSCA section 4(a)(1)(B) statutory requirements.

At EPA ’ s request, the ITC encourages manufacturers of these chemicals to visit the EPA ’ s HPV Challenge Program web site ( http://www.epa.gov/opptintr/chemrtk/ volchall.htm/ ) and to make a commitment to sponsor these chemicals at the present time, before regulatory actions are initiated. EPA will initiate development of TSCA section 8(a) PAIR and 8(d) HaSDR rules soon after these chemicals are added to the Priority Testing List and the ITC ’ s 55 th Report is published in the Federal Register . Also at EPA ’ s request, the ITC encourages the submission of robust summaries of studies submitted under the TSCA section 8(d) HaSDR rule to facilitate EPA ’ s review of the unpublished TSCA section 8(d) studies (see USEPA. 1999. Draft Guidance on Developing Robust Summaries. October 22, 1999 ( http:/ /www.epa.gov/chemrtk/robsumgd.htm/ )). While some of the HPV orphan chemicals have been previously added to the TSCA section 8(d) HaSDR rule, all of the sunset dates for these chemicals have expired (see Appendix A of this report), thus new and so far unreported studies would need to be submitted. Information about the environmental fate and potential hazards associated with these chemicals when combined with information about exposure and uses will allow the EPA and others to evaluate and prioritize potential health and environmental effects and determine the need for test rules under TSCA section 4(a). If you have any questions regarding the applicability of this action to a particular entity, consult the technical person listed under **FOR FURTHER INFORMATION CONTACT** .

4. Information needs . For each individual substance listed in Appendix A of this report, EPA needs the following information to assess the extent and degree of exposure and potential hazard associated with these substances:

a. Production, importation, processing, use and associated exposure information that is captured under the TSCA section 8(a) PAIR form.

b. Unpublished studies of: i. Physical/chemical properties and environmental fate for the properties listed in 40 CFR 716.50 as well as melting point and boiling point.

ii. Health effects including pharmacokinetics, genotoxicity, acute toxicity, subacute toxicity, subchronic toxicity, chronic toxicity, reproductive toxicity, developmental toxicity, immunotoxicity, neurotoxicity, and oncogenicity/carcinogenicity.

iii. Ecological effects including acute and chronic toxicity studies of aquatic and terrestrial vertebrates and invertebrates and aquatic plants.

c. Only studies where the recommended HPV orphan chemical is ≥ 90% of the test substance by weight should be submitted. In VerDate jul<14>2003 16:41 Feb 10, 2005 Jkt 205001 PO 00000 Frm 00005 Fmt 4701 Sfmt 4703 E:\FR\FM\11FEN3.SGM 11FEN3

## 7368 Federal Register / Vol. 70, No. 28 / Friday, February 11, 2005 / Notices addition, only studies that were conducted using TSCA, Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), Organization for Economic Cooperation and Development (OECD), or other internationally accepted test guidelines or voluntary consensus standards should be submitted. Studies performed where the recommended HPV orphan chemical is < 90% of the test substance by weight are not requested at this time. B. Chemicals Removed From the Priority Testing List

1. 3-Amino-5-mercapto-1,2,4-triazole . 3- Amino-5-mercapto-1,2,4-triazole (Chemical Abstracts Service Registry Number (CAS No.) 16691 –43 – 3 ) was added to the Priority Testing List in the ITC ’ s 42 nd Report to obtain annual production/importation volumes and trends, use, exposure, and health effects data (Ref. 9). The addition was based on concerns that 3-amino-5-mercapto-1,2,4-triazole was structurally related to 3-amino-1,2,4-triazole (Amitrol  ), a herbicide that affects thyroid hormone activity (Ref. 10). In response to the ITC ’ s request, the EPA added 3-amino-5- mercapto-1,2,4-triazole to the July 24, 2000, PAIR rule (Ref. 11) and the May 4, 2004 HaSDR rule (Ref. 5). Numerous studies were submitted in response to the HaSDR rule. These studies are summarized in this unit. 3- Amino-5-mercapto-1,2,4-triazole was positive in the mouse bone marrow micronucleus test, clastogenic to rat lymphocytes, but not mutagenic in the Ames assay using strains TA98, 100, 1535, and 1537 or in the E. coli assay, using strain WP2 uvrA-. 3-Amino-5- mercapto-1,2,4-triazole was a mild eye and skin irritant, but not a skin sensitizer. In a 4- week inhalation study the no observed effect level of 3-amino-5-mercapto-1,2,4-triazole was 20 milligram/meter cubed (mg/m 3 ).

3-Amino-5-mercapto-1,2,4-triazole is being removed from the Priority Testing List because information submitted in response to the PAIR rule suggested that 3-amino-5- mercapto-1,2,4-triazole is an on-site intermediate and the production/importation volumes were lower than the 250,000 pounds of 3-amino-5-mercapto-1,2,4-triazole imported into the United States in 1993 (Ref. 9).

2. Glycoluril . Glycoluril (CAS No. 496

–46 – 8) was also added to the Priority Testing List in the ITC ’ s 42 nd Report to obtain annual production/importation volumes and trends, use, exposure, and health effects data. The addition was based on a potential for human exposure and a suspicion of carcinogenicity (Ref. 9). In response to the ITC ’ s request, the EPA added glycoluril to the July 24, 2000 PAIR rule (Ref. 11) and the May 4, 2004 HaSDR rule (Ref. 5). No studies were submitted in response to the HaSDR rule.

Glycoluril is being removed from the Priority Testing List because information submitted in response to the PAIR rule suggested that glycoluril is an on-site intermediate and the production/importation volumes were less than the 10,000 to 1,000,000 pounds of non-CBI annual production/importation volumes reported to the EPA in 1986, 1990, and 1994 (Ref. 9).

3. Benzenamine, 3-chloro-2,6-dinitro-N,Ndipropyl-4-(trifluoromethyl)- . Benzenamine, 3-chloro-2,6-dinitro-N,N-dipropyl-4- (trifluoromethyl)- (aka 3-Chlorotrifluralin (CAS No. 29091

– 20 – 1) was added to the Priority Testing List in the ITC ’ s 48 th Report to obtain information on uses, exposures, environmental releases, pharmacokinetics, subchronic toxicity, mutagenicity, reproductive and developmental effects, carcinogenicity, and ecological effects (Ref.12). Benzenamine, 3-chloro-2,6-dinitro-N,Ndipropyl-4-(trifluoromethyl)- was added to the Priority Testing List because it has an estimated bioconcentration factor (BCF) of 7,700 and is a chlorinated analog of trifluralin (CAS No. 1582

– 09 – 8), the herbicide that causes adverse effects in experimental animals and is considered to be a possible human carcinogen by the EPA (Ref. 12).

In response to the ITC ’ s request, the EPAadded benzenamine, 3-chloro-2,6-dinitroN,N-dipropyl-4-(trifluoromethyl)- to the June 11, 2003 PAIR rule (Ref. 4) and the May 4, 2004 TSCA section 8(d) HaSDR rule (Ref. 5). No information was submitted in response to the PAIR or HaSDR rules. The ITC isremoving benzenamine, 3-chloro-2,6-dinitroN,N-dipropyl-4-(trifluoromethyl)- from the Priority Testing List because the PAIR rule did not provide any additional exposure information implying that benzenamine, 3- chloro-2,6-dinitro-N,N-dipropyl-4- (trifluoromethyl)- is not produced at greater than 1,000 pounds per site.

4. Stannane, dimethylbis[(1- oxoneodecyl)oxy]- . Stannane, dimethylbis[(1- oxoneodecyl)oxy]- (CAS No. 68928

– 76 – 7) was added to the Priority Testing List in the ITC ’ s 49 th Report to obtain use, exposure, environmental fate, health effects, and ecological effects data (Ref. 13). Stannane, dimethylbis[(1-oxoneodecyl)oxy]- was added to the Priority Testing List because it has an estimated BCF of 8,600 and signs of toxicity, including neurotoxic effects that were observed in a rat oral gavage study (Ref. 13).

In response to the ITC ’ s request, the EPA added stannane, dimethylbis[(1- oxoneodecyl)oxy]- to the June 11, 2003 PAIR rule (Ref. 4) and the May 4, 2004 TSCA section 8(d) HaSDR rule (Ref. 5). No information was submitted in response to the HaSDR rule. The ITC is removing stannane, dimethylbis[(1-oxoneodecyl)oxy]- from the Priority Testing List because the information submitted in response to the PAIR rule suggested that the production/importation volumes of stannane, dimethylbis[(1- oxoneodecyl)oxy]- were not greater than the 10,000 – 500,000 pounds of non-CBI production/importation volumes reported to the EPA in 2002 ( http://www.epa.gov/oppt/ iur/iur02/index.htm/ ). 5. Benzene, 1,3,5-tribromo-2-(2- propenyloxy)- . Benzene, 1,3,5-tribromo-2-(2- propenyloxy)- (CAS No. 3278

– 89 – 5) was added to the Priority Testing List in the ITC ’ s 50 th Report to obtain use, exposure, environmental fate, health effects, and ecological effects data (Ref. 14). Benzene, 1,3,5-tribromo-2-(2-propenyloxy)- was added to the Priority Testing List because of an estimated BCF of 4,000 and potential for exposure from its use as a flame retardant for expanded polystyrene insulation board (Ref. 14).

In response to the ITC ’ s request, the EPA added benzene, 1,3,5-tribromo-2-(2- propenyloxy)- to the June 11, 2003 PAIR rule (Ref. 4) and the May 4, 2004 TSCA section 8(d) HaSDR rule (Ref. 5). Information submitted in response to the HaSDR rule indicated that the concentrated chemical may be slightly irritating to the skin. The ITC is removing benzene, 1,3,5-tribromo-2-(2- propenyloxy)- from the Priority Testing List because the information submitted in response to the PAIR rule suggested that the production/importation volumes of benzene, 1,3,5-tribromo-2-(2-propenyloxy)- were not greater than 10,000

– 500,000 pounds of nonCBI production/importation volumes reported to the EPA in 2002 ( http:// www.epa.gov/oppt/iur/iur02/index.htm/ ). 6. 1-Triazene, 1,3-diphenyl- . 1-Triazene, 1,3-diphenyl- (aka diazoaminobenzene (CAS No. 136 – 35 – 6) was added to the Priority Testing List in the ITC ’ s 50 th Report to obtain annual production/importation volumes and trends, use, exposure, and health effects data (Ref. 14). 1-Triazene, 1,3-diphenyl- was added to the Priority Testing List because it is a predicted carcinogen based on its metabolism and similarity in toxic effects to benzene and aniline (Ref. 14).

In response to the ITC ’ s request, the EPA added 1-triazene, 1,3-diphenyl- to the June 11, 2003 PAIR rule (Ref. 4) and the May 4, 2004 TSCA section 8(d) HaSDR rule (Ref. 5). No information was submitted in response to the PAIR or HaSDR rules. The ITC is removing 1-triazene, 1,3-diphenyl- from the Priority Testing List because the PAIR rule did not provide any additional exposure information implying that 1-triazene, 1,3- diphenyl- is not produced at greater than 1,000 pounds per site.
